Zuckerberg’s Got a Psycho: When you’ve got millions of “Friends” at your disposal, you’re bound to stumble across a few loonies — just ask (alleged) Facebook founder Mark Zuckerberg.

The billionaire TIME Magazine Person of the Year 2010 has taken out a restraining order against a San Francisco man he claims is stalking him and his assistant/sister, Randi, by bombarding The Zuckerbergs with threatening messages in person and via private messages on Facebook.

Pradeep Manukonda, 31, has been ordered to stay at least 300 yards from Mark and his family until a court hearing later this month. Cops in Palo Alto, California first made contact with Manukonda in January, after he began randomly showing up at Facebook Headquarters in Downtown San Francisco to ask budding philanthropist Mark to donate cash to his family. Despite receiving a verbal warning from police, Pradeep continued harassing The Zuckerbergs, even sending flowers to Mark’s home late last month.

In one of his Facebook messages to Mark, Pradeep writes: “Please help me, then I am ready to die for you….Please understand my pain.”

That’s all the incentive Mark needed to seek an order of protection.

We wonder if there’s a clause about “poking” in this restraining order?
